Mortgage and Property Tax Calculator Ontario

This mortgage and property tax calculator for Ontario helps you estimate your monthly mortgage payments and annual property taxes. Simply enter your home price, down payment, interest rate, amortization period, and property tax rate to get accurate financial projections.

How to Use This Calculator

To calculate your Ontario mortgage and property taxes:

Enter the purchase price of your home in Canadian dollars.
Specify your down payment amount or percentage.
Input your mortgage interest rate (fixed or variable).
Select your amortization period (typically 25 or 30 years).
Enter your property tax rate (varies by municipality).
Click "Calculate" to see your estimated monthly payment and annual property tax.

The calculator will display your total monthly payment (including principal, interest, and property tax) and your annual property tax amount. You can also view a breakdown of your mortgage payments over time.

Formula Used

The calculator uses the standard mortgage payment formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ] Where: M = Monthly payment P = Principal loan amount (Purchase price - Down payment) i = Monthly interest rate (Annual rate / 12 / 100) n = Number of payments (Amortization period × 12)

Property tax is calculated as:

Annual Property Tax = (Purchase Price × Tax Rate) / 100

Monthly property tax is then divided by 12 to include in the total monthly payment.

Worked Example

Let's calculate for a $500,000 home with a 20% down payment, 5% interest rate, 25-year amortization, and 1.2% property tax rate:

Down payment: $500,000 × 20% = $100,000
Principal: $500,000 - $100,000 = $400,000
Monthly interest rate: 5% ÷ 12 = 0.4167%
Number of payments: 25 × 12 = 300
Monthly payment: $400,000 [ 0.004167(1.004167)^300 ] / [ (1.004167)^300 - 1 ] ≈ $2,850.00
Annual property tax: ($500,000 × 1.2) ÷ 100 = $6,000
Monthly property tax: $6,000 ÷ 12 = $500
Total monthly payment: $2,850 + $500 = $3,350

This example shows you would pay approximately $3,350 per month for a $500,000 home in Ontario with these terms.

Assumptions

Frequently Asked Questions

What is included in the monthly payment?: The monthly payment includes principal, interest, and property tax. Additional costs like closing fees are not included in this calculation.
How does the amortization period affect my payments?: A longer amortization period means lower monthly payments but more interest paid over time. A shorter period results in higher monthly payments but less total interest.
Can I change the interest rate after taking out the mortgage?: Variable rate mortgages allow rate changes, while fixed rate mortgages maintain the same rate. Check your mortgage terms for specific conditions.
Are property taxes included in the mortgage balance?: No, property taxes are separate from the mortgage balance. They are paid annually and included in your monthly payment as a fixed amount.
How accurate is this calculator?: This calculator provides estimates based on standard mortgage formulas. For precise figures, consult with a mortgage professional or use your lender's exact calculations.
